Multiple Sounddevices

Assuming you have a soundcard and an usb-Headset which may or may not plugged in at boottime. The order of sounddevices will not be consistent because, if plugged in at boottime, the usb-device is loaded at first by the hotplug-mechanism.Solution: Manually set the default order of the sounddevices.
As "root"-user, look what devices are avilable.
